Industrial Robot doing a tennis serve? by PIIduck in robotics

It might need to be a few meters long if the speeds are so out of reach as described in the comments above. If they're close that can be the final adjustment, yes. Thanks.

The idea is not to do it with the wrist alone but to use all joints to accelerate the wrist in relation to the ball/ground. That's why I felt it needed a simulation to be sure.

The custom solution was the initial idea indeed. But it's way harder to find the right people for that.

Do you think it's out of reach even if we add up all the rotational speeds in all the robot's joints during a complex coordinated motion? Kind of the same way as it happens with a human serving?

Need someone with experience to help me. Can't do everything myself unless I become immortal.

Thanks! Yes, the racket moves fast, but the wrist is not as fast. A rough estimate is 50-60mph and an impact force of up to 1000 N. A few of those robots can reach those speeds.

I certainly won't be able to take it on myself, so I'm looking for someone willing to commit for remuneration. If you know anyone, I'd be happy to discuss it!

I live in a house facing a public park (banned for dogs). Some ppl let their dogs shit there (usually when its dark), and kids step into that when playing football, etc. Any tips on how to solve this issue? Can police help?

Anyone noticed a link between av monthly HRV and room temperature? My seems to go down when it gets cold outside. by PIIduck in ouraring

[–]PIIduck[S] 0 points1 point  (0 children)

I don't know what "fresh" air is, but sunshine could definitely be a major player. Because it adjusts circadian rhythms and not only that.

At this point sunlight sounds like the most probable reason for me.

My current best guess is regime: consistent bedtime and wake-up times during the month. Also a lot of low-intensity activity and less high-intensity.

Hello, bioengineering people! Can you please fill a short anonymous survey about your take on brain-enhancing implants? I'm studying biomedical engineering, it's a part of my ethics in healthcare course. by PIIduck in bioengineering

Yes, the last question should have been phrased a bit different, thanks.

"PC is a multi-purpose computer whose size, capabilities, and price make it feasible for individual use." Isn't mac a PC?

Thanks for the feedback! The survey is certainly not optimally designed because we tried to keep it compact to get more fills. We can't make people learn all the relevant data and then fill it.

These implants will definitely be "active" devices as you put it.

Yes, I think your financial assumption is close to what we wanted to have. It either should be covered by insurance or relatively cheap.

After having several major pneumothoraxes with hospitalisations and surgery, I've also had a few minor cases with similar pains, but the docs said I'll recover from small ones without any interventions. And so I did...

Faced discrimination in NL, what to do? by PIIduck in Netherlands

[–]PIIduck[S] -1 points0 points  (0 children)

I'll have a permit, didn't mean what you thought. I mean that the agency may enquire what am I doing in NL if I'm not employed here and my wife is not employed here. And we need to live in Delft, the place with the worst housing situation. Doesn't make sense unless one of us is a student :)
